Samarium Cobalt Block & Bar Magnets

Samarium Cobalt (SmCo) block & bar magnets are strong permanent magnets that offer excellent magnetic stability in high or very low temperature environments. Part of the rare earth magnet family, SmCo block magnets have superior magnetic properties compared to other permanent magnet materials because of their high-resistance to corrosion or demagnetization. From medical devices to high-performance motors and sensor systems, samarium cobalt magnets are ideal for technical applications where magnetic stability is critical in extreme temperatures and space is a limiting factor.

We carry a large inventory of Samarium Cobalt (SmCo) Block & Bar Magnets, not all of which are shown on this website. Contact us today or send us a special request and let us know what you are looking for.

Approximate Pull Info for SmCo Magnets

The approximate pull info listed for SmCo disc magnets are for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure. (top)
